Abstract

This invention provides an electronic blood pressure meter which can measure blood pressure with great accuracy. The angle of inclination is detected by inclination sensor and the height of the limb where the measurement is to be taken is obtained from this angle of inclination. An MPU determines whether the height which is obtained is within a specified difference from the height of the heart. The result of this determination is communicated via display or buzzer.

Claims

1. An electronic blood pressure meter, comprising:

a cuff device which, when fastened to a given part of a body, extracts data concerning pulsewave information found in said given body part;

a device which measures either a blood pressure or condition of blood vessels based on said extracted pulsewave information;

a posture detecting device which detects the posture of said given body part by detecting the height of said body part on which a blood pressure measurement is being performed; and

a judging device which judges whether said detected posture is appropriate.

2. The electronic blood pressure meter according to claim 1, wherein said posture detecting device detects the inclination of said given body part.

3. The electronic blood pressure monitor according to claim 1, wherein said cuff device is movable relative to said device which measures either a blood pressure or condition of blood vessels.

4. An electronic blood pressure meter, comprising:

a cuff device which, when fastened to a given part of a body, extracts data concerning pulsewave information found in said given body part;

a device which measures either a blood pressure or condition of blood vessels based on said extracted pulsewave information;

a posture detecting device comprising a heart sound sensor which detects the posture of said given body part; and

a judging device which judges whether said detected posture is appropriate.

5. The electronic blood pressure meter according to claim 4, further comprising:

a height difference detector for detecting the height difference between the height of a heart of the body and the height of the body part at the detected posture,

wherein the judging device judges whether the detected posture is appropriate based on the detected height difference.

6. The electronic blood pressure monitor according to claim 4, wherein said cuff device is movable relative to said device which measures either a blood pressure or condition of blood vessels.
